[php] PHP中遍历关联数组的三种方法

方法1：foreach

<?php $sports = array( 'football' => 'good', 'swimming' => 'very well', 'running' => 'not good'); foreach ($sports as $key => $value) { echo $key.": ".$value."<br />"; } ?

 

方法2：each

<?php $sports = array( 'football' => 'good', 'swimming' => 'very well', 'running' => 'not good'); while ($elem = each($sports)) { echo $elem['key'].": ".$elem['value']."<br />"; } ?>

 

方法3：list & each

<?php $sports = array( 'football' => 'good', 'swimming' => 'very well', 'running' => 'not good'); while (list($key, $value) = each($sports)) { echo $key.": ".$value."<br />"; } ?>
